Belt problem?
I just had my machine start jumping a little as seen in the video linked. You can hear it sound like maybe the belt is slipping. What would you say the issue is?
Thank you!

Re: Belt problem?
Not the belt. The stepper motor is losing steps. Could be one of more of the following: mechanical obstruction, binding, and insufficient stepper current.

I checked for obstructions and have not found anything. Would a loose cable cause the current issue?
The machine has been running well and just started acting up today.

Re: Belt problem?
What's the motor driver resolution? I mean the micro step. 1/8 or 1/16?
And, what is motor current? Speed ?
"um" value?
Good grounding?
Also,check the axial coupling as it may got loose

Factory motors.
I have the upgraded DSP kit you sell. It has been running fine.
Where should I check the ground?
Axial coupling looks good.
The side to side seems to be the issue.
Do the motors just crap out?

Re: Belt problem?
Ok so I discovered that the X axis will stop working after a few runs while the Y still works. If we power the machine off and back on it works again.
Any tips?

Re: Belt problem?
I don't know if your motor run out or not. That's why I asked for your setting information see if any hint that lead to the problem.
Please reply with the info I requested. Or, I have no idea what you're running with

I have had it about 5 months now so its not terribly old.
So when I swap microstepper drivers I have the same results so its not the driver.

Re: Belt problem?
Check the motor temperature, you should be able to touch it for more than a few seconds. If you can't, reduce the stepper current. If a stepper motor overheats, it won't work correctly.

I should answer Marco's question - he really does know what he's talking about and why he asked it!

Re: Belt problem?
After a lot of work I believe we have narrowed it down to the axis stepper motor wiring. I believe the wiring on the X-Axis motor is shorting out or something of that nature.

Re: Belt problem?
You may request a RMA for return for exchange of a new DSP controller
I'm in China now so I can't assist you at this movement but my staffs there should be able to help for the exchange

Re: Belt problem?
I would suspect a bad stepper motor before the wiring, unless its in a connector. You swapped the driver boards around and still had the same problem, correct? So its either the wiring, a connector or the motor.TimAustinTX wrote:After a lot of work I believe we have narrowed it down to the axis stepper motor wiring.
